Hi Chad,

I tried to address your concerns in r170336.

I have left most of the changes, as seen in the diff below, between r170103 (before my initial change), and r170336. I hope that all of them now are safe. Please tell me if you still have concerns.

Sorry! My understanding of FastISel is limited, and these changes was obviously too aggressive. I can also see more changes that are wrong. I will go through all changes for FastIsel again, and try to correct this.

Patrik,
I have a few concerns here.  See comments inline below.

This will hit:
Assertion failed: (isSimple() && "Expected a SimpleValueType!"), function getSimpleVT, file /Users/mcrosier/llvm-clean/llvm/include/llvm/CodeGen/ValueTypes.h, line 661.
